Nondestructive Testing of Concrete Elements and Structures
Quality of a concrete structure depends on good construction practice. On the other hand, continuous repair and maintenance preserve the quality of construction. Nondestructive evaluation...
Evaluating Spillway Adequacy
More than a third of all dam failures are caused by overtopping. Equipment malfunctions or operations errors are sometimes to blame, but the principal cause is inadequate spillway capacity....
New Hong Kong International Airport
The airport at Kai Tak has served as a viable commercial operation since the lat 1930s and has played a pivotal role in the territory's development. The fact that Kai Tak has a finite...
The Future Role of Factory Built Housing
For most of this century, and particularly around 1970 as epitomized by Operation Breakthrough, the concept of transitioning the US housing industry from stick-by-stick field building...
Customer Requirements in Industrialized Housing
Residential construction efforts in the U.S. are highly fragmented, and this has slowed the application of new technologies. While there has been an increase in the use of manufactured...
Computer Modeling of Structural Systems for Residential Scale Buildings
The majority of housing in the United States is single family residences or low-rise multiple family dwelling units. The structural systems usually consist of rather uncomplicated types...
Evaluating the Effectiveness of Transportation Control Measures for San Luis Obispo County, California
The San Luis Obispo Air Pollution Control District has developed simple techniques to estimate emission reductions from various Transportation Control Measures. Accurate emission estimates...
Laboratory Tests of Modal Emissions and Off-Cycle Corrections to FTP-75
The modeling of emissions from on-road mobile sources is an on-going process. Two broad topics which are currently under study are the evaluation of driving cycles and the development...
Developing Protocols for Motor Vehicle Air Quality Modeling
This paper is directed to air quality analysts. It examines the issues surrounding a modeling protocol and how to work effectively with a traffic engineer on a project to model carbon...
The General Theory of Quantitative Risk Assessment
From the many individual applications of quantitative risk assessment (QRA) that have been made in various fields, this paper abstracts and lifts out the concise, simple, and elegant cluster...
Aversion to Epistemic Uncertainties in Rational Decision Making: Effects on Engineering Risk Management
When faced with epistemic uncertainties in a decision problem, subjective expected-utility theory (SEU) implies that the only relevant characteristic of these uncertainties is the mean...
On Deciding Between the Use of Engineering Standards and Risk Analysis
Risk analysis offers advantages for the optimal design and maintenance of infrastructure, but it is not always practical to apply due to the nature of certain types of infrastructure....
System Engineering and Risk
System engineering means many things to many people, but there is a large group of practicing engineers in the defense and energy sectors who define system engineering as a structured...
Remediation Site Prioritization by the Risk Ranking and Filtering Method
The risk ranking and filtering (RRF) method, developed for ranking critical components of the NASA Space Shuttle, is a possible framework for the prioritization of hazardous-waste sites...
The Role of Risk Analysis in Feasibility Studies of Water Resources Projects
Many parameters involved in feasibility studies of water resources projects are inherently uncertain. Projections of these parameters based upon extension of past trends can be quite inaccurate....
Optimal Allocation of Resources in Repair and Maintenance of Bridge Structures
The structural design process, examined in its entirety (and taking into account the uncertainty and randomness that characterize the governing parameters) is a decisional process, involving...
Linearisation and Offshore Fatigue Reliability
In determining the force effects due to wave action on offshore structures it is conventional to use an equivalent linearisation to convert wave velocities to forces via Morison's equation....
Reliability Analysis of Lunar Structures Under Meteoroid Impact
The United States is slowly moving towards lunar base, and possibly Mars base, activities. Design of structures for these bases requires knowledge about loadings and conditions which in...
Probabilistic Analysis of Post-Tensioned Steel Girder Bridges
External post-tensioning is used as a means of strengthening existing steel girder bridges. Since absolute safety of structures is impossible to attain due to uncertainty in load and resistance,...
Fuzzy Measures in the Knowledge Based Diagnosis of Seismic Vulnerability of Masonry Buildings
Rules based expert systems and fuzzy logic have been employed to increase the speed and the reliability of the survey of masonry buildings, to forecast their seismic vulnerability....
